Capabilities: Scalability

Keep ALL of your data—up to hundreds of terabytes—instantly available in RAM distributed across any size server array and cloud environment

Scalability without bounds

Enterprise Ehcache gives business-critical applications the capacity for non-disruptive, cost-efficient growth and migration to cloud environments. Whether you have tens of Gigabytes or hundreds of Terabytes of data, Enterprise Ehcache with BigMemory can store it all in-memory for a fraction (factor 10-100) of the servers needed by classic P2P in-memory grids like Oracle® Coherence.

This is because of its unique ability to use ALL the RAM available on each server in the cluster. No other in memory solution on the market compares!

Cost-efficient capacity

As your data and number of users skyrocket, so can expenses. Enterprise Ehcache helps you keep those costs in check in two ways:

  • Enabling cost-efficient scale out using commodity servers.

The solution’s unique tiered architecture allows high-performance access to very large caches without requiring hundreds of servers to fit all of the cache in memory. Also, the software maximizes memory utilization—so you can cache even more data on less hardware.

  • Reducing your reliance on expensive databases.

Enterprise Ehcache with BigMemory can help you save in software licenses, hardware costs and ongoing administration. Some of our customers have slashed their database costs in half, with some avoiding more than $10 million in expenses a year.

Enterprise Ehcache lets you also steer clear of costly, time-consuming code re-writes, which alternative scaling approaches require.

Bottom line: Enterprise Ehcache is the most effortless, flexible and cost-efficient way to scale enterprise applications.

Flexible scale-up / scale-out architecture

Enterprise Ehcache has a flexible, multi-tier architecture that lets you add capacity when and where it’s needed. Not only Enterprise Ehcache lets you seamlessly add more memory storage capacity directly on your applications servers for ultra-low data access latency (up to the RAM available), but it also allows for massive scale-out to handle larger workload without a sweat. Similar to RAID, the Enterprise Ehcache cluster is configured into groups of servers to form mirrored stripes. You can easily add more stripes on demand to increase throughput and total addressable cache size.

Business Value

Use Enterprise Ehcache to speed up your applications. You’ll achieve dramatic performance gains with a scalable caching architecture that provides efficient access to large data sets.

Decouple from hard-to-scale and costly database

Databases are often the primary culprit when application performance declines. As processing needs and data volumes grow, it simply takes too long to perform complex database queries, convert data into application objects, read from an external disk and make round-trips to the database.

Enterprise Ehcache with BigMemory overcomes the performance and scalability limitations of databases. Using Enterprise Ehcache to offload the database, you can reduce the time required to complete individual transactions by as much as 90 percent. Plus, you can slash your spending on database licenses, hardware and maintenance—saving millions of dollars.

Use Case: One large U.S. law enforcement agency adopted Enterprise Ehcache to create a 500-gigabyte in-memory data store, complete with an analytical engine and SQL-like search capabilities.

Help scale your applications with blazing fast data access

Enterprise Ehcache with BigMemory stores large amounts of data closer to the applications that need it, so requests for that data can be served more quickly. The results are immediate and significant: Enterprise Ehcache with BigMemory reduces application response times by orders of magnitude—10-fold or more—and dramatically improves throughput and latency.

What’s more, these gains are sustained as the application scales. With Enterprise Ehcache, you have a long-term solution for dynamic, no-compromise growth up to 100s of Terabytes of Data!

Use Case: A major Healthcare Federal Web application desperately needed to achieve scalability – publically suffering from poor response times, unmet SLAs and frequent down times due to high user request loads.

Meet your SLA’s consistently

With complexities increasing and data growth exploding, it is a real challenge for many applications to meet all their Service Level Agreements (SLAs), all the time. Maybe it’s a result of a usage spike that pushes applications into long garbage collections, or a network issue, a disk failure, or a slow database…any of which can greatly affect SLAs through poor response times, and ultimately poor user experience. The business impact of un-met SLAs can vary widely, from simple user frustration to millions of dollars in lost revenue.

By using Enterprise Ehcache with BigMemory, you can easily offset a lot of these potential issues by storing more data in-memory right where the application needs it for ultra-fast and reliable access, effectively ensuring better and more consistent low response times, all the time!

Use Case: Enterprise Ehcache with BigMemory helped meet SLAs and save millions of dollars for a leading credit card company whose cards are accepted at millions of merchant locations and more than 845,000 ATMs in more than 185 countries.

Use Cases

A large U.S. law enforcement agency adopted Enterprise Ehcache to create a 500-gigabyte in-memory data store, complete with an analytical engine and SQL-like search capabilities.

The agency turned to Enterprise Ehcache with BigMemory when their architected database backend could not handle and scale to the 10-fold growth in the volume of data it had ingested daily since 2011—more than 100 gigabytes per day, or the equivalent of 1 million new records. The agency’s 500-gigabyte in-memory data store allows new information to be accessed and queried almost immediately by agents in the field or analysts in the office.

Enterprise Ehcache opens up the ability for this customer to have a tremendous amount of information at their disposal, in-memory, and in real-time.


A major Healthcare Federal Web application desperately needed to achieve scalability—publically suffering from poor response times, unmet SLAs and frequent down times due to high user request loads.

Enterprise Ehcache with Bigmemory was then introduced to help scale the site to 200+ nodes, while making 300GB worth of in-memory data available to each node in order to tremendously offload and reduce database requests, as well as decrease dramatically the network pressure on critical hardware such as firewall and routers.

The benefits were immediate and highly visible with consistently high performance and availability despite 10x increase in user traffic. Average response time consistently below 500ms even at 100k TPS peak loads (>10x improvement). All achieved with very minimal code and application impact!


A leading credit card company whose cards are accepted at millions of merchant locations and more than 845,000 ATMs in more than 185 countries leveraged Enterprise Ehcache with BigMemory to help meet SLAs and save millions of dollars.

The company determined that it was failing to meet its one-second SLA for identifying blacklisted credit cards approximately 0.3 percent of the time—which adds up when you’re dealing with thousands of transactions every second. This resulted in blacklisted cards being improperly accepted, costing the company an estimated $10 million annually.

The causes were twofold. First, the company kept its list of seven million blacklisted card numbers and individuals in a disk-bound Oracle® database, which was slow to access. Second, the Java® garbage collector caused extended, unpredictable pauses. Each pause forced the company to “guess” on many transactions, exposing the company to losses.

Since putting BigMemory live in production, the company meets its SLA more than 99.995 percent of the time. The company’s significant store of in-memory blacklist data is protected by BigMemory’s persistent storage and fault-tolerant, fast-restartable architecture—so machines coming back online after an outage don’t demand a full reload from the database. WAN replication keeps its global data centers in sync, making it easy to redirect traffic from one to another in case of outages or heavy loads.

The solution is performing so well that the company plans to power its fraud detection application with BigMemory in the near future.
